Specification of Letters Patent.

Patented Nov. 26, 1907.

Application filed September 11. 1906. Serial No. 334.175.

To all whom it may concern:

Be it known that I, JOHN E. HARKER, a citizen of the United States,residing at Milford, in the county of Dickinson and State of Iowa, haveinvented a new and useful Sight for Firearms, of which the following isa specification.

My invention relates to rear detachable single barrel shot gun sightsand has for its object to provide a detachable sight which can bereadily attached and detached from the ordinary single barrel take downshot gun, and which presents a perfectly flat top to the sightwith agroove therein for the purpose of enabling the marksman to take a better and quick sight, and to prevent cross firing.

With this object in view, my invention consists in the novelconstruction of the detachable sight.

Referring to the accompanying drawing: Figure 1 is a perspective View ofa shot gun barrel showing rear detachable sightin position thereon. Fig.2 is a perspective view of the detachable rear sight, and Fig. 3 is atop plan of the sight showing barrel broken away and a portion of thesight broken away. Like numerals of reference indicate the same partsthroughout the several figures in which;

1 indicates a shot gun barrel and 2 the rear detachable sight, said reardetachable sight being as shown in Fig. 2 constructed of a thin metalband having the top portion 3 formed perfectly flat, and a sightinggroove 4 formed centrally in the top 3. WValls 5 cut to conform to theshape of the barrels are arranged under the top 3 for the purpose ofstrengthening the same and for holding the sight snugly in position. 011one side 6' of the band forming the sight is provided a spring 7 whichis preferably formed integral with the band and may be suitably securedthereto if desired. This spring 7 is curved inwardly at 8 as clearlyshown at Fig. 2, said spring 7 entering a notch 9 in the gun as shown inFigs. 1 and 3.

In attaching the sight the barrel is detached from the stock of the gunin the usual method and the sight is placed on the barrel raising thespring 7 and pushing same slightly forward; the barrel is then replacedon the stock and the sight is pulled back until the spring 7 drops intothe notch 9 thus securely holding the sight in position and preventingaccidental movement thereof.

In detaching the sight the spring 7 is raised and the sight pushedforward as before cited; the barrels are then detached from the stockand the sight is slipped off the barrels and the barrels again replacedon the stock in the usual manner.

Having thus fully described my invention what I claim as new and desireto secure by Letters Patent of the United States is:

A detachable rear gunsight having a flat upper surface provided with asighting groove, said sight comprising a band arranged to be passed overthe end of the gun barrel, and a spring'carried on said band arranged toenter a notch on the gun barrel for securely holding the sight inposition, substantially as described.

In testimony whereof, I afhx my signature, in presence of two witnesses.

JOHN E. I-IARKER.
